Hey Tech Help

I just got my new rear bush-bearing for my 08 KTM 300 from Suttos and want to know if I can replace the old one without takin the swing arm off.

The last time I had to do this was on me old 300 and I just put the swing arm in the shop and they done all the bushes-bearings.

I was intending to get the whole kit for the swing arm cause I thought that was how ya bought em but after speaking with Suttos they suggested that I replace the bottom shock one first as this is were all the movement is. Any advise would be very much appreciated.

:laugh:

Hey Dusty
Have done many of said bushes
Never tried to change one without removing the swingarm though
With the swingarm out you can line it up over an open vice with a near sized socket and tap it out. A second pair of hands to balance the swingarm is handy. Like White rocket said remove the bush and seal from one side first. I have found that a few good solid hits gets the bugger moving, imagine it would be awkward still on the bike. Fit the new one measuring each side to centralise it.
Bloody expensive bush but at least there is only one
Cheers

Hey White rocket
How did the nylon bearing go, was thinking of machining some up. Would still need the steal inside sleeve that runs over the bolt I would imagine???

Was thinking teflon to be too soft Dude
Works well in normal bushes but not sure about the impact that this bush is subjected too
Could maybe make a couple of each and test them hey

All done fellas. Left the swing arm on the bike and used your idea Murph with the socket. It worked like a beauti. I had to give it a few good hits until it loosened up and started to move but nothin to extreme. I think i’ll take it off next time though mainly for the convinience of having it in me hands to put the new one in which was a bit tricky doin on the bike. Anyway it all worked out well so thanks for the advise….Dusty

Guys, you can get a neoprene sock which covers the joint and stops most of the crap getting to the bush and wearing them out.

I had one on mine for a couple of years and never had a problem.

Also you must not oil or lubricate the heim joint as they are a nylon type bush – the oil holds any dust/dirt and acts like grinding paste to wear out the joint.

I have done a couple of them over the years just using a socket and extension bar to knock them out with the swing arm still in the bike without any problems. Just place the bike on the bike stand, unbolt the shock, lift it out then drive out the old bush and fit in new one. Should only take about half an hour and a couple of beers
